Every developer knows the frustration of trying to share a local project with a teammate or client. Whether you are building a custom web app, testing webhooks, or running local AI models, exposing your localhost to the public internet has historically been a headache.
Most existing solutions require you to download bulky CLI tools, sign up for restrictive accounts, or deal with random, ugly URLs that change every single time your connection drops. When you are in the zone, this friction slows down your momentum and disrupts your development workflow.
That is why we were incredibly excited to discover tunnl.gg. It is a brilliant, lightweight utility that solves this exact problem by providing stable localhost URLs over SSH with no installs required.
Because the platform runs entirely over SSH, you do not need to download, install, or configure any third-party software on your machine. You simply run a single, standard SSH command in your terminal, and tunnl.gg instantly routes your local port to a public, secure URL.
One of the most powerful features of this tool is its ability to generate persistent, stable URLs. Instead of dealing with randomized links that break constantly, you get a reliable endpoint that stays the same, making it much easier to test integrations over time.
This stability is especially game-changing for AI developers and prompt engineers. If you are running local LLMs or AI APIs using tools like Ollama, you can easily expose your local endpoints to external testing environments or frontends without any setup hassle.
Additionally, tunnl.gg prioritizes security by leveraging your existing SSH keys to authenticate your sessions. You get a blazing-fast, secure tunnel to your local machine without exposing your system to unnecessary security vulnerabilities.
This tool is a perfect fit for web developers who need to quickly demo features to clients without deploying to a staging server. It is also an invaluable asset for backend engineers who need to test webhooks from third-party services like Stripe or Twilio.
